I strongly urge you to report this incident to CHP or the Sheriff, whomever will claim jurisdiction. To capture the vehicle(license) and the drivers face in one photo is a rarity, and will go a long way in negating the vehicle owner operator from saying it wasn't them driving or their vehicle. Hopefully, if the elements of a crime are present something positive will happen. At least the driver can be ID'd in the event there are other reports at a later date.

Good job on taking the photo.
